Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture feeding equipment, and in particular to an aquaculture feeding equipment. Background Technology

[0002] With the rapid development of the aquaculture industry, traditional manual feeding methods are no longer sufficient to meet the demands of large-scale, precision farming. Manually scattering feed presents problems such as high labor intensity, low feeding efficiency, and uneven feed distribution. Especially in large-scale aquaculture ponds, this can easily lead to localized feed surpluses causing water pollution, or insufficient feeding hindering the growth of farmed organisms.

[0003] In existing technologies, the feeding mechanism is easily affected by feed moisture and particle shape. Single vibration or auger structure is prone to bridging and blockage, and the lack of internal wall cleaning device leads to residual mold. The throwing component adopts a fixed design, which cannot dynamically adjust the throwing angle and diffusion range according to the shape of the aquaculture pond and the needs of the organisms. Fixed installation or simple wheel structure is difficult to adapt to complex terrain, and different feed characteristics are not considered, resulting in low feeding accuracy and serious feed waste, which restricts the large-scale and intelligent development of aquaculture and has poor practicality. Therefore, this utility model discloses an aquaculture feeding device to solve the problems of poor feeding, uncontrollable throwing, poor environmental adaptability and low feed utilization of existing equipment. Utility Model Content

[0013] This invention utilizes a first rotating roller integrated with a cleaning scraper and stirring rod, coupled with precise control by a servo motor. This not only breaks down deposits on the bin walls in real time during feeding but also prevents feed clumping through dynamic stirring. The second rotating roller features a conical spiral blade design whose diameter automatically changes with the material level, ensuring real-time matching between the discharge port cross-sectional area and material flow rate. Furthermore, the synergistic effect of the L-shaped cleaning scraper and the inclined scraper automatically cleans residue from the bin walls after each feeding cycle, reducing the risk of mold growth and providing a reliable guarantee for precise feeding.

[0014] To address the uneven coverage issue caused by the fixed design of existing spreading components, this invention innovatively employs a multi-dimensional adjustable spreading mechanism.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0024] This utility model provides, for example Figures 1 to 4 The aquaculture feeding device shown includes: a base 1, an mounting column 2 installed on the upper surface of the base 1, a first mounting frame 3 installed on the upper part of the mounting column 2, and a second mounting frame 4 installed on the lower side wall of the first mounting frame 3 on the mounting column 2. A storage tank 5 is installed at the other end of the second mounting frame 4, an upper cover 6 is installed on the upper part of the storage tank 5, a feeding pipe 8 is installed on the feeding pipe 8, and a support frame 17 is installed in the middle of the upper surface of the base 1. A feeding component is provided on the mounting column 2 to make the storage tank 5 feed evenly. A sprinkling component is provided on the support frame 17 to sprinkle the feed provided by the feeding component. This utility model, by setting a cleaning scraper 10 integrated with a first rotating roller 9 and a stirring rod 11, and cooperating with a servo motor for precise control, can not only break up the attached objects on the bin wall in real time during the feeding process, but also prevent feed from clumping through dynamic stirring. The conical spiral blade 13 of the second rotating roller 12 automatically changes its diameter according to the material level, ensuring real-time matching between the cross-sectional area of ​​the discharge port and the material flow rate. Furthermore, the synergistic effect of the L-shaped cleaning scraper 10 and the inclined scraper 14 automatically cleans residue from the bin walls after each feeding cycle, reducing the risk of mold growth and providing a reliable guarantee for precise feeding. Addressing the uneven coverage problem caused by the fixed design of existing sprinkling components, this invention innovatively adopts a multi-dimensional adjustable sprinkling mechanism. Through the linkage mechanism of the upper / lower adjusting plate 25 and the transmission system of the threaded column 20-connecting rod 19, precise adaptation of the sprinkling angle and diffusion range is achieved. Multiple independently controlled trumpet-shaped sprinkling troughs 27, combined with the synchronous drive of the adjusting ring 18, ensure uniform feed distribution, effectively solving the problem of insufficient or excessive feeding in the corner areas of large-scale aquaculture ponds.

[0025] Furthermore, in this example, such as Figure 1 and Figure 2As shown, the feeding assembly includes a first servo motor 7, which is mounted on a first mounting bracket 3. The output end of the first servo motor 7 is installed in the middle of the upper cover 6, and a through circular hole is provided on the upper cover 6 corresponding to the position of the output end of the first servo motor 7. The output end of the first servo motor 7 is rotatably installed in the circular hole, and a first rotating roller 9 is installed at the output end of the first servo motor 7. A second rotating roller 12 is installed at the other end of the first rotating roller 9, and a cleaning scraper 10 is installed on the upper outer wall of the first rotating roller 9. An inclined scraper 14 is installed at the other end of the cleaning scraper 10. Multiple sets of stirring plates are evenly arrayed on the outer wall of the first rotating roller 9 located below the cleaning scraper 10. The mixing rod 11 and the outer wall of the second rotating roller 12 are equipped with spiral blades 13. The lower end of the storage tank 5 is conical, and the cleaning scraper 10 is L-shaped with its side wall attached to the inner wall of the storage tank 5. The oblique scraper 14 is attached to the bottom inner wall of the storage tank 5, and a through hole is provided at the bottom of the storage tank 5 corresponding to the positions of the second rotating roller 12 and the spiral blade 13. The maximum diameter of the spiral blade 13 is the same as the diameter of the hole, and the outer wall of the spiral blade 13 is attached to the inner wall of the hole. The first servo motor 7 is mounted on the first mounting bracket 3, and its output end passes through the through hole on the upper cover 6 and is connected to the first rotating roller 9 to provide power for the entire feeding assembly. When the first servo motor 7 is started, it will drive the first rotating roller 9 to rotate. The upper outer wall of the first rotating roller 9 is equipped with an L-shaped cleaning scraper 10, and the side wall of the cleaning scraper 10 is attached to the inner wall of the storage tank 5. During the rotation of the first rotating roller 9, the cleaning scraper 10 rotates accordingly, scraping away feed adhering to the inner wall of the storage hopper 5 in real time to prevent feed accumulation on the hopper wall. Simultaneously, an inclined scraper 14 is installed at the other end of the cleaning scraper 10. The inclined scraper 14 is in contact with the bottom inner wall of the storage hopper 5. After each feeding cycle, the inclined scraper 14 automatically cleans the residue on the hopper wall, reducing the risk of feed mold. Multiple sets of stirring rods 11 are evenly arrayed on the outer wall of the first rotating roller 9 located below the cleaning scraper 10. When the first rotating roller 9 rotates, the stirring rods 11 dynamically stir the feed in the storage hopper 5, preventing feed clumping, ensuring feed flowability, and facilitating subsequent even feeding. A second rotating roller 12 is installed at the other end of the first rotating roller 9, and a spiral blade 13 is installed on the outer wall of the second rotating roller 12. The lower end of the storage bin 5 is conical, and a through hole is provided at the bottom corresponding to the position of the second rotating roller 12 and the spiral blade 13. The maximum diameter of the spiral blade 13 is the same as the diameter of the hole, and the outer wall of the spiral blade 13 is attached to the inner wall of the hole. When the second rotating roller 12 rotates with the first rotating roller 9, the spiral blade 13 will rotate accordingly, thereby achieving uniform material feeding.

[0026] Furthermore, in this example, such as Figure 3 and Figure 4As shown, the spraying assembly includes a second servo motor 22, which is mounted in the middle of the support frame 17. A rotating disk 28 is mounted on the output end of the second servo motor 22. A receiving trough 29 is formed in the middle of the upper surface of the rotating disk 28. Multiple spraying troughs 27 are evenly arrayed on the rotating disk 28 centered on the receiving trough 29. The spraying troughs 27 are funnel-shaped, with the small opening of the spraying trough 27 connected to the receiving trough 29 and the large opening of the spraying trough 27 facing outward. A receiving plate 16 is mounted on the upper surface of the rotating disk 28. The middle of the upper surface of the receiving plate 16 is a slightly concave conical shape. Furthermore, a circular channel is provided on the rotating disk 28 corresponding to the receiving trough 29, and a circular mounting plate 15 is installed on the top of the receiving disk 16. The center of the circular mounting plate 15 is open. An adjustment mechanism is installed on the side wall of the rotating disk 28 corresponding to the position of each set of spraying troughs 27. The adjustment mechanism includes an upper adjustment plate 23, which is installed on the upper port position of the side wall of the rotating disk 28 corresponding to the upper port position of each set of spraying troughs 27. A lower adjustment plate 25 is installed on the side wall of the rotating disk 28 corresponding to the lower port position of the spraying trough 27. A hinge 26 is installed at the position where the upper adjustment plate 23 connects to the rotating disk 28. A hinge 26 is installed at the position where it connects with the rotating disk 28. Side plates 24 are slidably engaged at both ends of the upper adjusting plate 23 and the lower adjusting plate 25. A connecting post 21 is installed on the upper end of the upper adjusting plate 23. An adjusting ring 18 is installed on the upper end of multiple sets of connecting posts 21. A set of connecting rods 19 is installed on the inner wall of the adjusting ring 18 at the opposite positions. A threaded post 20 is threaded onto the other end of the connecting rod 19. One end of the threaded post 20 is rotatably engaged on the ring mounting plate 15. The upper adjusting plate 23 and the lower adjusting plate 25 are provided with width and side plate dimensions corresponding to the positions of the side plates 24. The plate 24 has the same width as the groove, and the length of the groove is shorter than the length of the side plate 24. The adjusting ring 18 has circular holes with the same diameter as the connecting posts 21 at each corresponding position. The connecting rod 19 has threaded holes that fit the threaded posts 20 at each corresponding position. The ring mounting plate 15 has circular grooves with the same diameter as the threaded posts 20 at each corresponding end position. The second servo motor 22 is installed in the middle of the support frame 17, and its output end is connected to the rotating disk 28 to provide power to the scattering assembly. A receiving trough 29 is located in the middle of the upper surface of the rotating disk 28. Feed falls from the feeding assembly and enters the receiving trough 29. A circular channel is located on the rotating disk 28 corresponding to the receiving trough 29. A receiving plate 16 is installed on the upper surface of the rotating disk 28, and its upper surface has a slightly concave conical shape in the middle to facilitate feed flow from the receiving trough 29 into the scattering trough 27. An adjustment mechanism is installed on the side wall of the rotating disk 28 corresponding to the position of each group of spraying troughs 27. The adjustment mechanism includes an upper adjustment plate 23 and a lower adjustment plate 25.An upper adjusting plate 23 is installed on the side wall of the rotating disk 28 at the upper end of each spraying trough 27, and a lower adjusting plate 25 is installed on the side wall of the rotating disk 28 at the lower end of each spraying trough 27. The upper adjusting plate 23, the lower adjusting plate 25, and the rotating disk 28 are all connected by hinges 26, and side plates 24 are slidably engaged at both ends of the upper and lower adjusting plates 23 and 25. A connecting post 21 is installed on the upper end of the upper adjusting plate 23, and an adjusting ring 18 is installed on the upper end of multiple connecting posts 21. When the spraying angle needs to be adjusted, rotating the threaded post 20 causes the adjusting ring 18 to rotate the upper adjusting plate 23 and the lower adjusting plate 25 around the hinge 26 via the connecting post 21, thereby changing the spraying angle of the spraying trough 27. A set of connecting rods 19 are installed on the inner wall of the adjusting ring 18 at opposite positions. A threaded post 20 is threaded onto the other end of each connecting rod 19, and one end of the threaded post 20 is rotatably engaged on the ring mounting plate 15. An annular mounting plate 15 is installed on top of the receiving plate 16, with its central part open. Rotating the threaded post 20 causes the connecting rod 19 to shift vertically, as the post 20 is threadedly connected to the connecting rod 19 and engages with the annular mounting plate 15. This movement of the threaded post 20 causes the connecting rod 19 to shift vertically, thereby moving the adjusting ring 18 up and down. The up-and-down movement of the adjusting ring 18 causes corresponding displacement of the upper adjusting plate 23 and the lower adjusting plate 25 via the connecting post 21, thus changing the opening direction of the spreading trough 27 and adjusting the diffusion range. Multiple sets of trumpet-shaped spreading troughs 27 are evenly arrayed on a rotating disk 28 centered on the receiving trough 29. The smaller end of the spreading trough 27 is connected to the receiving trough 29, while the larger end faces outwards. When the second servo motor 22 drives the rotating disk 28 to rotate, the feed in the receiving trough 29 enters the spreading trough 27 and is scattered out through the larger end of the spreading trough 27. Because multiple sets of scattering troughs 27 are independently controlled and synchronously adjusted by the threaded column 20, the scattering angle and diffusion range can be precisely matched, so that the feed is evenly distributed and the problem of insufficient or excessive feeding in the corner areas of large-scale breeding ponds can be effectively solved.
